CEFR Levels Explained: What A1, A2, B1, B2, C1, and C2 Mean
The CEFR levels are a six-stage scale — A1, A2, B1, B2, C1, C2 — used to describe how well someone can understand and use a language, from complete beginner (A1) to near-native mastery (C2). It's the reference system behind most English courses, textbooks, and exams, so knowing where you sit on it tells you what to study next.
What Are the CEFR Levels?
CEFR stands for the Common European Framework of Reference for Languages. It splits language ability into three bands — A (Basic User), B (Independent User), C (Proficient User) — each split again into two levels, giving six total: A1, A2, B1, B2, C1, C2.
Instead of grading grammar knowledge in isolation, CEFR levels describe what you can actually do with the language: hold a simple conversation, follow a news broadcast, write a formal email, argue a nuanced point. That's why schools, employers, and exam boards (IELTS, TOEFL, Cambridge English) all map their own scoring back to it — it's the shared vocabulary for "how good is your English."
The CEFR Levels Explained: A1 to C2
Here's what each level means in practice, plus a rough, commonly-used vocabulary size for orientation — treat the numbers as ballpark, not a hard test threshold, since different courses count "known words" differently.
| Level | Name | Rough vocabulary | What you can do |
|---|---|---|---|
| A1 | Beginner | ~500–1,000 words | Introduce yourself, ask simple questions, understand basic phrases |
| A2 | Elementary | ~1,000–2,000 words | Handle routine tasks: shopping, directions, simple past/future talk |
| B1 | Intermediate | ~2,000–3,000 words | Travel independently, describe experiences, follow the main points of familiar topics |
| B2 | Upper Intermediate | ~4,000–5,000 words | Discuss most topics fluently, understand TV news, write clear reports |
| C1 | Advanced | ~8,000 words | Use language flexibly for work and study, understand implicit meaning, near-natural pace |
| C2 | Proficiency | ~16,000+ words | Understand virtually everything, express nuance, indistinguishable from an educated native speaker in most contexts |
A1 — Beginner
You can understand and use familiar everyday expressions and very basic phrases: your name, where you live, simple needs. Conversations only work if the other person speaks slowly and helps you out. Browse the A1 vocabulary library to build the core words this level is built on.
A2 — Elementary
You can communicate on simple, routine tasks — shopping, local geography, employment, immediate needs. You describe your background and surroundings in short, simple terms, but longer or unfamiliar topics still break down quickly. The A2 library hub groups the next tier of vocabulary by topic.
B1 — Intermediate
This is the "independent traveler" level. You can deal with most situations likely to arise while traveling, produce simple connected text on familiar topics, and describe experiences, events, and ambitions with basic reasons and explanations. Most general English courses treat B1 as a solid working level. See the B1 vocabulary hub for topic-organized sets at this stage.
B2 — Upper Intermediate
You can understand the main ideas of complex text, including technical discussion in your field, and interact with fluency and spontaneity that makes regular interaction with native speakers feel natural for both sides. You can produce clear, detailed text on a wide range of subjects. Many university and job-application English requirements sit at B2. Explore the B2 library hub.
C1 — Advanced
You can understand a wide range of demanding, longer texts and recognize implicit meaning — tone, subtext, register. You express yourself fluently and spontaneously without obviously searching for words, and use language flexibly for social, academic, and professional purposes. Most "fluent for work" job requirements target C1. Check the C1 library hub.
C2 — Proficiency
You understand with ease virtually everything heard or read, summarize and reconstruct information from different spoken and written sources coherently, and express yourself spontaneously, very fluently, and precisely — differentiating finer shades of meaning even in complex situations. Few learners need C2 for practical purposes; it's the ceiling of the scale, not a common target.
How Do I Find Out My CEFR Level?
The fastest way is a short placement test that adapts to your answers rather than a self-assessment guess — most learners overestimate or underestimate their own level, especially at the boundaries (is that B1 or B2?). Take Budling's free English level test to get a CEFR estimate in a few minutes, then jump straight to vocabulary sets matched to that level.
If you'd rather explore by topic first, the vocabulary library organizes sets by both level and subject — useful if you already know roughly where you sit and want to fill specific gaps (travel words, business English, phrasal verbs).
How Do You Move Up a CEFR Level?
There's no shortcut around exposure and practice, but the structure of how you study matters:
- Study vocabulary at your current level, not above it. Working through a B2 word list when you're solidly A2 mostly builds recognition of words you can't yet use — the level hubs above exist so you study the right tier.
- Use active recall, not passive review. Reading a word list repeatedly builds false confidence; testing yourself against it builds actual memory. See how to remember English vocabulary for the specific techniques that work.
- Review on a schedule, not all at once. Spaced repetition spreads reviews out so words move from short-term recognition to long-term recall — it's the difference between "I studied this" and "I know this."
- Consume real content slightly above your level. Graded readers, shows with subtitles, articles on familiar topics — comprehensible input at "current level + a bit" is what pushes vocabulary and grammar forward.
- Re-test periodically. Levels aren't permanent labels; retake a placement test every few months to confirm you've actually moved, not just to feel like you have.
Progress between levels isn't linear — A1 to A2 is typically much faster than B2 to C1, because higher levels demand more vocabulary, more nuance, and more exposure hours per level gained. Don't expect the same pace throughout.
What's the Difference Between B1 and B2 English?
B1 gets you through familiar, everyday situations with simple, connected sentences — you can travel, describe experiences, and follow the gist of straightforward conversations. B2 is a step up in both range and fluency: you can follow complex arguments, discuss abstract topics, and hold a spontaneous conversation with a native speaker without either side working hard to communicate. The practical marker most learners notice: at B1 you're often translating or planning sentences before speaking; at B2 that gap mostly closes.
Do CEFR Levels Match IELTS or TOEFL Scores?
Exam boards publish their own approximate mappings between their scores and CEFR levels — for example, Cambridge English exam boards commonly align IELTS bands with CEFR levels, with higher bands corresponding to B2, C1, and C2. Because scoring rubrics differ, treat any exam-to-CEFR mapping as an approximation for planning purposes, not an exact conversion — always check the specific exam board's official guidance for the mapping they publish.
Can I Skip a CEFR Level?
Not meaningfully. Levels build on each other — B2 assumes the vocabulary and grammar patterns of B1 are already automatic, not just recognizable. What can happen is uneven skill development: someone with strong reading comprehension at B2 might still speak at a B1 level if they've had little speaking practice. A placement test that only measures one skill (reading, for instance) can overstate your overall level — worth keeping in mind when you self-assess.
Not sure where you land on the scale yet? Take the free English level test — it takes a few minutes and points you straight to vocabulary sets matched to your actual level, so you're not guessing at A1 when you're really B1 (or the other way around). Your pixel pet levels up as you review, so the studying that gets you to your next CEFR level looks a little less like a chore along the way.
